What term refers to the change of form in adjectives and adverbs to show amount or quantity?

The term that refers to the change of form in adjectives and adverbs to show amount or quantity is "comparison." Comparison involves altering the base form of these words to indicate different degrees or levels of an attribute. For example, when using the adjective "tall," we can form the comparative "taller" to compare two entities and the superlative "tallest" to compare three or more entities. Similarly, adverbs can change form to indicate comparison, such as "quick" becoming "quicker" and "quickest." This serves to establish distinctions in the degree to which an adjective or adverb describes a noun or verb.

In contrast, the other options do not accurately define this specific function. "Integration" pertains to combining parts into a whole, "modification" refers more generally to making changes or adjustments, and "condensation" involves reducing something in volume or density, which does not relate to the grammatical changes in adjectives and adverbs for comparison purposes.
